+++ This bug was initially created as a clone of Bug #1221889 +++

Description of problem:
Log mknod failure due to EEXIST in DEBUG level in protocol/client.

Without this, there would be excessive logging of EEXIST errors from
protocol/client,server in logs of sharded volumes when multiple attempts are
made from the same mount to create /.shard or the individual block shards as
part of inode write fops.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
